    I'm using a Power Mac G4 "Sawtooth" and have a newly installed 500 GB hard drive. Since this is older technology, my Mac only sees the drive as 128 GB. I purchased and installed the Intech ATA Hi-Cap Extender driver to break the limit. I understand I have to partition the drive... however when I try to do this in Disk Utility, the partition maps are grayed out and cannot be changed. The drive is showing up as 465 GB so the extender did work half way.

    Any ideas? If it means formatting the drive, that's not a problem. I have yet to transfer my personal files over. Any help would be great.

    I installed a SIIG brand PCI card into my Sawtooth to get by the 120gb limit. Never had any success with the drivers, but this was a long time ago. Also I never wanted to mess with that because of unforeseen problems or loosing data if the system had to be reinstalled [or if you had data past the 128gb limit and it "went missing"].

    Either way, as far as I know the best [only?] way to successfully partition a drive through DiskUtility is to format it. There might be some software that can do it "on the fly" as bootcamp does but I'm not familiar with such a thing. What format is the drive anyway?
